Romans 10:9
that if you will confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
Paul urges a confess and believe that is worked out in limits and longings in Romans 10:9—look for "confess" and "mouth". Give confess and believe in conversations that test patience—steady the will with prayer.
The setting is Romans—epistle/letter, developing confess and believe. Read in Romans 10, its force becomes clearer. Listen for “confess” alongside “mouth”.
